Table 3. Top five important variables from built-in feature selection with different models.

Method	1	2	3	4	5
SVM	Age	FAC	TAPSE	S’	HTN
GLM	Age	FAC	DL	DM2	HTN
RF	Age	FAC	TAPSE	S’	HTN
ELASTICNET	DL	FAC	Smoker	DM2	HTN

A Seed of [123] was fixed for all methods with set. Seed function in R. SVM, support vector machine; GLM, generalized linear method; RF, random forest; HTN, hypertension; DM2, diabetes mellitus type 2; DL, dyslipidemia; FAC, fractional area change, TAPSE, tricuspid annular plane systolic excursion, S, S-wave velocity.
